F'RICIIONAL CONTACT WINDOW GUIDE.

Application nieuwe 2s, 1924. serial No. 721,641.

To all whom t may cof/wcm.'

Be it known that' I, HOWARD D. RANDALL, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in a Frictional Contact Window Guide, of which the following is a specification.

My invention as embodied in disclosure is concerned with providing a yielding structure for use as a guide, channel or run, in which glass window plates, such as are used in the doors and windows of sedan automobiles, may be retained and l5 reciprocated. It will be readily evident that the invention lends itself to other uses, and that the form ofthe yielding structure may be modified to adapt same to various other uses.

An object of my invention is to provide a structure which, when developedk into a channel for guiding reciprocating plate glass windows and the like, will exert a yielding pressure upon the glass, thereby precluding rattling thereof.

Another object of my invention is to provide a structure forthe pnropse stated that may vbe exed in anyI direction, whereby to facilitate positioning thereof in the doors of so automobile bodies.

Another object of my invention is to provide a structure of the class described that may be economically and expeditiously produced and applied. l

Another object. ot-iny invention is to provide a structure wherewith a positive spring .contact may be effected with the sides o1 the glass and the like.

These and other' objects are attained by the means described herein, and disclosed in the accompanying drawings, in which:

Fig. 1 is a view showing the elements of a device embodying miy invention in position preparatory to mounting thereof, one upon the other.

Fi 2 is an end view of the parts shown in Fig. 1.

Fig. 3 is a vperspective view of the parts shown in Figs. 1 and 2, atersame has been developed into a channel preparatory to mountmg thereof upon a vehlcle `door or frame.

Fig. 4 is a fragmental perspective view, part in section, showing a structure as dlsthe instant HEISSUED closed in Fig. 3 Ain position in a door, and operative upon a fragment of avplate glass. Fig. 5 is an end view of a modified form of device embodying my invention.

Briefly my structure comprises a wire mat or core 12 for which a. flexible covering 11 is provided. The core 12 is produced preferably from wire, havingdesired spring characteristics, and is bent backwardly and forwardly in the manner disclosed in Fig.` 1 for providing a substantially fiat rectangular wire mat. 'Ihe wire 10 may be of any suitable cross section and the particular configuration of the various loops developed along the lateral edges of the wire mat may be varied and modified t'o meet various conditions. The flexible covering 11 is preferably provided on its inner face with an adhesive so that when the wire mat 12 is placed'upon the iexible covering l1, and the lateral ends 13 and 14 of the flexible material are bentover the wire mat, the adhesive will serve to bind the opposed portions of the flexible material, where such sections contact through the openings 15 formed interiorly of the loops 16 developed along the lateral edges of the wire mat 12. In Fig. 2, the ends 13 and 14 are shown in dotted lines in their fixed positions relative to the underlying position 17 of the covering material. The structure, after fixa tion of the ends 13 and 14, is then belet to the desired form, Jfor example to the channel forms shown in Figs. 3 and 5, whereupon the charmel may be inserted in the run or way 18 that forms part of a vehicle door or the like, and in which the plateglass window 19 or the like is received. It will be readily evident that the fiexible material 11 may be reinforced by capping the looped ends 12 of the Wire mat prior to the turning inward of the lateral edges 13 and 14 of the exible material 11. It will be readily evident that the flat structure disclosed in Fig. 2, after the 'ends 13 and 14 are afiixed, may be developed into various flexible forms other than the channel 20, wherefore I do not restrict my'invention to the specific form into which such flat structure might be developed.

Although the invention as disclosed herein comprises spring wire having resilient qualities, it will be readily evident that under some circumstances such qualitiesv might be undesirable, wherefore it is not intended to restrict the invention to a struc intermediate portions thereof for providing.

ture wherein the wire is resilient or yielding.

l/Vhat I claimI is:

1. As a new'article of manufacture a channel comprising a flexible covering, and a resilient mat contained within the covering and comprisinga continuous spring wire extending in alternate directions, and having its lateral edges disposed at angles to the the side walls of the channel.

2. A channel structure of U shaped cross section comprising a resilient wire mat and a flexible covering for the mat, thel mat comrising a serpentine Wire looped along its ateral edges and having its lateral edges turned relative to the intern'iediate'or base portion thereof, whereby the lateral `portions of the wire mat form part of the arms of the channel and reta-in the lateral e'dges of the flexible covering at an angle to the center portion of the covering, the said lateral edges of the wire mat and flexible covering providing a way between them through which Way a sliding member may be moved, the arms of the channel yieldingly resisting movement of suoli sliding member.

3. A channel structure of U shape cross section comprising a resilient Wire mat and a covering for the mat, the mat and covering being relatively fixed, the mat having its lateral edges turned at an angle and overhanging the intermediate portion or base of the structure for providing a 4way Wider at its bottom than at its top and for yieldingly resisting movement of a sliding member through lthe way.

In testimony whereof, I have hereunto subscribed my namethis 20th day of June,

HOWARD DRANDALL.
